Here is mine... 100% done by myself (but patterned after Markus's original design). Ported through rear deck. Sealed from trunk (no rattles and very quiet in trunk while pounding inside of the car). Phoenix Gold Titanium amps, Eclipse 12" subs, 1.1cf/chamber, Focal comps in front and Alpine 2 ways in back. Hit 139.6db. SQ is EXCELLENT! Entire trunk and interior is double layered with fatmat sound killer.
I like showing it off, but not posting it much due to the amount of Q's that I get. Difficult to explain the full setup. I'll post pics in a couple of responses to give as much detail as possible to help answer questions...

Panel Mounts. Everything is hinged and swings up to get to adjustments and wires.
